about the FAQ "POV-Ray/raytracing on GPU" I am actually quite curious 
how many systems would actually support double precession floating point 
types (as needed by POV-Ray) and how *fast* they are.

If you are not using Windows(tm) there is no need to read on because
Apple's OpenCL implementation does currently not support 64bit floats 
anyway and the same is AFAIK true for any Linux system. This might and 
should change in the future but this is the current situation.

I've written a simple Windows program (a kind of "realtime" Mandelbrot 
explorer) that is meant to check the capabilities of your system.

You can download it here (please check the included readme.txt)

and send an email to me (ive[at]lilysoft[dot]org) or maybe simply reply 
to this post. My guess is that both the availability and performance 
gain will be quite disappointing.


thanks a lot
